1.0 INTRODUCTION Description: The MS10 is a magnetically isolated single pole double throw point level switch. When the MS10 is inserted into a process vessel or external chamber it can sense high or low levels within the vessel. The unique magnetic isolation action eliminates the need for such things as seals, diaphragms, springs, or torque tubes because there is no physical contact with the process. he MS10 typically requires no preventive maintenance since it is totally sealed. The switch is not protected against radiation, electro-magnetic devices, parmeant magnets or excessive mechanical vibration.

Operation: The MS10 will provide either a normally open or normally closed dry contact, which may be used to activate external devices such as alarms or solenoids. The capacity of the switch allows for control of a wide range of de-vices. Maximum voltage and current ratings are listed in the specification section of this manual. Variations in proc-ess fluid specific gravity (0.4 minimum clean fluid SG) have minimal effect because of the small size of the integral float. The float tracks the liquid level and provides for an electrical contact output (SPDT). These contacts are suitable for use with alarms and/or to activate a pump motor starter relay.

Installation: The MS10 is mounted to the process vessel via the integral 1-1/2” MNPT fitting. Suitable reducers and/or adapters may be used provided they do not interfere with the full stroke of the float. The MS10 should be tightened such that the electrical connection is at its uppermost position. The following procedures outline the steps necessary to install the switch. WARNING! MAKE SURE CIRCUIT IS DE-ENERGIZED WHILE INSTALLING THE SWITCH.

1. Inspect the switch for any signs of damage incurred during shipment. Mount the switch in a process connection at the point in which you want the switch to trip. Use of a suitable lubricant/sealing compound is recommended. During final tightening, align the MS10 electrical connection to the topmost position as shown (Figure 1). A 2" wrench is needed for tightening. The electrical contacts may be installed either before or after installing the switch housing (Figure 2). Be sure to push the retainer assembly firmly into the switch housing during installa-tion. The retainer assembly may be removed to facilitate removal of the switch assembly, if necessary. Note: The MS10 will also function when the electrical connection is aligned to the lowest position (bottom), however the electrical contacts will function opposite of the diagram (Figure 3).

2. Connect the field wires to the wiring harness of the MS10 according to the application. Reference Figure 3 for proper operation of contacts. Be sure to adequately insulate all electrical connections.

3. The liquid level inside the vessel should be cycled above and below the switch and operation of the contacts should be verified.

4. The float of the switch shall always be mounted in a straight horizontal position, arrow pointing up, so that the float of the switch is allowed to move freely up and down with the process. Obstruction of the float will cause in-accurate and erroneous readings to be relayed by the switch that could cause a hazardous condition to develop.

5. Competent personnel should only perform installation and maintenance procedures on process control equip-ment and these switches.

6. Placement of switches should be only where the effects of a hazardous atmosphere will not effect the material integrity of the apparatus. It is a requirement the installation personnel to assure the hazardous atmosphere or the surrounding atmosphere will not compromise the long-term integrity (strength, conductivity, corrosion) of the switch material.

7. Warranty/Repair/Replacement:

8. For warranty, repair, or replacement of transmitter call the K-TEK service department at 225-673-6100. The ser-vice department is located in Prairieville, Louisiana 70769, USA.

9. The material construction of these units offers no particular protection against radiation, electro-magnetic or mechanical hazards. The construction of units is not designed to protect against other hazardous not defined in above sentence.

10. Strong magnetic fields should not be placed around the switch (reed switch is magnetically coupled) in order to prevent inaccurate and erroneous readings, which could cause a hazardous condition to develop.

11. Avoid aggressive substances that could drip, spill, pour, or fall on the switch and cause premature failure of the material or wiring resulting in inaccurate and erroneous readings which could lead to a hazardous condition.

Note: A.) Field wiring connected to the MS10 switch must comply with applicable sections of the National Electrical Code. Do not install/use in environments that would allow the metal of the switch to react with the contents (liquid or va-por) which could cause corrosion and metal fatigue.

4.0 MAINTENANCE

The MS10 does not require any routine maintenance in normal day to day operation. WARNING! If there is a need to take the switch out of service or disconnect it for any reason, then make sure the circuit is de-energized, or insure that the area is known to be non-hazardous! Handling & Storage Requirements: There are no special handling and storage requirements associated with this device.

5.0 APPENDIX Explosion Proof Installation: (Non-Intrinsically Safe Installation for ATEX IS Installations see page 7) Many of K-TEK’s switch products (MS10, MS30, MS50) are based on magnetically operated reed switches. Since reed switches have the inherent characteristic of very closely spaced switch contacts, it is extremely important to protect these contacts from high voltage transients caused by inductive loads. When an inductive load is de-energized, the collapsing magnetic field induces a high voltage of opposite polarity into itself and thus the switch. Two basic methods exist to clamp this voltage and thus protect the switch contacts.

D.C. Applications For D.C. applications, a diode is placed in parallel with the inductive load (note the polarity of the diode and power supply). A 1N4001 general purpose diode is normally sufficient to clamp the induced voltage of the inductive load to a safe level.

A.C. Applications For A.C. applications, a Metal Oxide Varistor (MOV transient surge suppressor) is placed either in paral-lel with the switch or the inductive load. The MOV changes from a high impedance to a very low imped-ance when the voltage across the MOV exceeds its rated voltage (the MOV rating must correspond with the power supply voltage). For 120 VAC control sys-tems a typical MOV would be the GE (General Elec-tric Co.) part number V130LA10A. In either case shown, the result is the limiting of the switch voltage to approximately 130 volts.

Explosion Proof Applications The switch has been rated for explosion proof applications by Factory Mutual (FM) and the Canadian Standards As-sociation (CSA) only. For typical/specific explosion proof installation see NEC 500 or NEC 505, or IEC directives. The MS10 is not approved for flameproof (European) application at this time. Intrinsically Safe Applications This switch is ATEX approved in IS installations (EEx ia) Zone 0 in Europe by DEMKO, in the U.S. by FM and in Canada by CSA This switch can be used in areas/processes that do not have explosive environments. For a typi-cally IS installation application please see the example below. If only two wires are used, then the 3

rd wire must be electrically and physically insulated from the circuit. For use with

three (3) wires, that is, use of the Normally Closed (NC) and Normally Opened (NO) contacts, a second IS barrier is required.

Replacement of switch (SPDT) on the MS10: * The MS10 switch must be replaced with K-Tek’s part number MS10-4 reed switch because the switch is potted for dimensions to fit inside of the SS tubing. Disconnect the power that runs through/to the switch (Assure that removing the power will not effect your process or process control) Lock-out and Tag-out the power so that power can not be applied to the switch until after the switch has been com-pletely repaired/replaced It is not necessary to remove the MS10 from the process to replace the reed switch Remove retaining ring with small screwdriver Remove the rubber grommet Pull out the magnetic reed switch by the wires Put in the replacement reed switch Replace grommet & retaining ring Disconnect the wires (2 or 3 wires) on old switch, noting the connections and colors, and re-connect the wires to the new switch according to hook-up of the old wiring. Ensure that the applied wattage & current do not exceed the power & current rating of the switch Remove the Lock-out / Tag-out device from the applied power Before applying power assure that this will not effect your process or process control Apply power and check the switch to assure that it is functioning properly Note: For the switch to operate (make and break contact) in the process, the fluid/process must be lower and raised above the level of the float.
